COMBINED VISE AND SCREW-CUTTING AND DRILLING DEVICE.

SPECIFICATION forming part of Letters Patent No. 418,637, dated December31, 1889.

l n Application filed June 6, 1889l Serial No. 313,297 (No model.)

To all whom it may concern.-

Be it known that I, JAMES O. BARRETT, a citizen of the United States,residing at Meadville, in the county of Crawford and State ofPennsylvania, have invented certain new and useful Improvements inCombination Vise and Screw-Cutting and Drilling Mechanism; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable ot-hers skilled in the art to'which it appertains to make and use the same. f

This invention relates to tools for the use of blacksmiths, gas, water,and steam fitter-s; and it consists in certain improvements in theconstruction thereof, whereby a combinationtool is produced, consistingof an iron-workers vise, a pipe-vise, and a screw-cutting and a drillingmachine, assembled in co-operative relation to each other in a unitarystructure.

The invention is illustrated in the accompanying drawings as follows:

Figure 1 is a top or plan view of the device. Fig. 2 is a verticalsection on the line 0c or:l in Fig. 1. Fig. 3 is a horizontal sectionthrough the screw-cutting and drilling mechanism.

A A A2 represent an ordinary iron-workers vise, in which are arrangedpipe-gripping jaws ct ce o.

B B B2 is the frame-work, in which is journaled a spindle C.

C is a crank for operating said spindle. F

marks a common ratchet device, also for op-y erating said spindle whenthe work is too heavy for operationby the crank.

E is a cam feed-lever.

The mechanism consisting of the spindle and the means for turning it maybe used either for drilling or screw-cutting, as desired. When used forscrew-cutting, a cutter-head D will be xed to the end of the spindle,and

when used for drilling a drill will be inserted in a stock or chuck onthe end of the spindle. The construction of these parts requires nospecial illustration or description, as they may be of the Inostordinary form.

A screw-cutting head D is shown in the drawings. In this head is shown aguide-mandrel G G', which enters the pipe to be screwthreaded. Thisguide will not be further described or claimed, as itis the propersubject of a separate application, which I reserve the privilege ofiiling hereafter.

When a drill is used on the spindle, it may be applied thereto the sameas the guide G G is shown to be applied.

On the side of the base A of the non-traveling jaw A of the vise thereis a wing A3, which may be cast integral with vthe jaw and base A A', orfirmly secured thereto, as `desired. This wing has outwardly-projectingflanges a4 a4 on its sides, as is seen in Fig. 2, and at the rear endthere are slots a3 through the iianges. The frame-piece B has a tongueh', which sets in between the iianges a4, and at its rear end there is apivot-pin b, which has its bearing in the slots c3 of the wing. Theframe-piece B also has a slot h3 through its foot horizontally, and abolt b2 passes through the wing A3 andthe slot b3.

It will be seen from the construction just described that theframe-piece or arm B can be bolted to the wing firmly by the bolt b2,and that it can be adjusted laterally' relative the spindle C intoaxi'al line with any sized -pipe that may be clamped by the jaws a a, a.

It will also be seen, and especially by observing the illustration inFig. l, that the arm B, when not held firmly against the wing A3 by thebolt b2, can be swung around on its pivot b, so as to carry the drillingand screw-cutting mechanisin out of the way of the vise when not in use.4

What I claim as new is- 1. In a tool for the purposes mentioned, thecombination, substantially as set forth, of a vise, an arm extendingfrom said vise at right angles to the plane in which the jaw of saidvise moves, and a drilling and screw-cutting spindle mounted on said armwith its axial line parallel with the faces of the jaws of said vise.

2. In a tool for the purposes mentioned, the combination, substantiallyas set forth, of a vise, a drill or screw-cutter spindle, and an arm orframe-piece supporting said spindle, which is connected with said viseand adjustable relatively to the movable jaws of said vise, whereby thesaid spindle may be adjusted upon the axial line of objects held withinsaid vise.

.y 3. In a tool for the purposes mentioned, the combination,substantially as set fort-l1, of a vise, a drill or screw-cutterspindle, and an arm or frame-piece supporting said spindle, which ispivotally connected with said vise and adjustable laterally therewithrelatively with the traveling jaw thereof, whereby the said spindle canbe adj usted in axial line with objects held within the jaw of the viseand beswung back out of position for action.

4. In a tool for the purposes mentioned, the combination, substantiallyas set forth, of a vise, a wing A3, connected with said vise, which setsat right angles to the grippingfaces of the jaws of said vise, an arm orframepiece B B B2, seated on said Wing and adjustable thereon relativelyto the movement of the movable jaw of said vise, and a spindle for'operating drills or screw-cutting dies journale'd in said 'arm orframe-piece with its axial line parallel with the faces of the jaws 0fsaid vise.

5. In a tool for the purposes mentioned, the combination, substantiallyas set forth, of the vise A A A2, with pipe-jaws a a a', the Win53r A3,secured to said vise and having flanges a4 with slots a3 therein, lthearm B, having tongue b {itt-ing between the flanges a, pivot b, seatedin the slots a3, slot b3, receiving the bolt b2 and arms B B2, and thespindle C, journaled in the arms B B2, and adapted, as shown, to operatescrew-cutters or drills upon obj ects held by the jaws of said vise,

In testimony whereof I alix my signature in presence of two witnesses.
